UNITED STATES PATENT OEEIcE..

THOMASl E. O. BRINLY, OF LOUISVILLE, KENTUCKY.

IM PROVEMEN'I' IN PLOWS.

Specification forming part of Letters Patent N0. 109,291, dated November15,1870.

To all whom it may concern:

Be it known that I, TEoMAs E. C. BRINLY, of Louisville, in the county ofJefferson and State of Kentucky, have invented certain Improvements inFlows 5 and I do herebydeclare that the following is a full, clear, andexact description thereof, reference being had to the annexed drawings,making part of this specication, in which- 1 Figure l is a perspectiveview of my improved standard with the share and moldboard attachedthereto. Fig. 2is another perspective view thereof, seen from the rear,and showing the parts in an inclined position. Fig. 3 is an elevationofthe standard, seen from the land side. Fig. 4t is an elevationthereof, seen from the opposite side. Fig. 5 is an elevation, seen fromthe land side, of part of the devices seen in'Figs. l and 2. Fig. 6 is aplan View of the share and landside detached. Fig. 7 is a plan view ofthe mold-board detached.

The same letters are used in all the figures in the designation ofidentical parts.

Thisinvention relates to plows, and my improvement consists in a novelmanner of firmly uniting the standard, share, landside,and moldboardtogether by means which will be more specifically pointed out in thesubjoined description and claim.

Io enable those skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

The standard or helve (marked A in the an-- nexed drawings) is providedat its upper end with the ordinary lange,A/,by which itisfirmly boltedto the beam of the plow. It is made of cast-iron, with a web of requiredthickness, and is strengthened by forming ribs a a along its edges, asshown. The forward edgeis beveled and curved to give the properinclination to the mold-board B and accommodate itself to its curvature.The upper end of said moldboard is bolted to a laterally-proj ectin gear, A2, of the standard, and a flange, A3, formed at the lower forwardedge of the latter, extends a sufficient distance under the mold-boardto give a firm support to the same at the lower end. This ange A3 is ofa triangular form in cross-section, as clearly shown in Fig. 2, its basebeing in a horizontal plane, or nearly so, and it is cast with aperturesa a in it passing through it in a nearly vertical direction from theside which supports the lower end of the mold-board to the base. Y

The share C, on the side or edge where it is jointed to the mold-board,is formed with a ange, C', extending to the rear, below thelatter, andso arranged as to lit with its upper surface nicely to the base of thetriangular lian ge A3 of the standard. Suitable holes having been boredin the moldboard and the ange of the share, opposite the holes a a inthe flange ofthe standard, the parts are firmly screwed together bybolts and nuts, the heads of the bolts being bent at an angle to theshank and countersunk in the mold-board so as to be flush with its uppersurface. The upper end ofthe .mold-board is at the same time bolted tothe ear A3. In this instance the land'sideD forms a part of theshare,being welded to the same, and the standard rests with its lower edgeupon the upper edge ofthe landside-bar when all the parts have beenunited together. To prevent the springing or bending of thelandside-barand to still more securely unite all the parts together, Iform an ear, A4, on the standard, as shown, and bolt the landsidethereto.

What I claim as my invention, and desire to secure by Letters Patent,is-

The standard A, constructed with the ears A2 and A4 and flange A3, incombination with the mold-board]3,a11ged share CO', and landside D, theparts being united together substantially in the manner set forth.

In testimony whereof I have signed my name to this specification in thepresenoeof two subscribing witnesses.
